From November 6, 2006.
It’s all relative. How many times have you heard that? Well, when you’re traveling close to the speed of light, everything really is relative; especially the passage of time. This week, Fraser and Pamela give you the skinny on Einstein’s Special Theory of Relativity. After listening to a few thought experiments, you too should be able to wrap your head around this amazing theory.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org
Today's 2 topics:
- Ten hours and 46 minutes after my Catalina Sky Survey teammate Greg Leonard discovered a Toyota RAV4 sized space rock, now named 2018 UA, streaking through the constellation of Pegasus at 8.8 miles/second, this tiny asteroid passed less than 1/2 the distance of the communications satellites to the surface of planet Earth.
- Aten Asteroids are stealthy space rocks which can be dim and hard to detect since for most of their path about the Sun their illuminated side is facing away from us.

Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. In this podcast, Dr. Roger Romani discusses the discovery of this system and what we can learn about massive black hole pairs from this system.
 
Bios: 
- Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.
- Dr. Roger W. Romani is a member of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University, where he has been Professor of Physics for over thirty years. His research interests center on black holes and neutron stars, which he and his research group study with a combination of telescope observations, from the ground and from space, and theoretical modeling.

From March 29, 2024.
One of our recurring topics is “Planet formation is not well understood,” and a trio of new papers is making it clear why planet formation continues to... not be well understood. Put simply: the Universe likes to create more diverse solar systems than an entire planet’s worth of sci-fi writers can imagine.

Paul Hill and Dr. Jenifer “Dr. Dust” Millard host. 
Damien Phillips, John Wildridge and Dustin Ruoff produce.
This month Dr. Jen is off to the US for the Solar Eclipse while Paul is just back from Goonhilly Earth Station. We chat about the imminent demise of the Chandra Space Telescope, more news on the Hubble tension, and of course the Great North American Eclipse. 
Chinese Lunar ambitions, Starship making it to space and the first Boeing Starliner crew make the news while in this month’s history moment we talk about the brightest Stellar event witnessed by humans.

Throughout human history, comets have fascinated us. They have gone from signs and portents of bad things to come to well-studied and even visited "dirty snowballs". Every year, observers search the skies, hoping to discover the Next Big Comet - Halley, Hyakutake, Hale–Bopp, McNaught. From SOHO and LINEAR to ATLAS and IRAS, numerous observatories have continued to add to the count of discovered comets. 
But it doesn't require expensive hardware or spacecraft to make similar observations from your own backyard; telescopes and even binoculars will work - at least for the brightest objects. For members of Unistellar's Citizen Science Network, however, comets can be seen at faint magnitudes under a range of night sky conditions.
 
Join Beth Johnson as she welcomes SETI Institute Postdoctoral Fellow Dr. Ariel Graykowski to this week's SETI Live to discuss the results of citizen scientist observations of comets 12P/Pons-Brooks and C/2023 A3 (Tsuchinshan-ATLAS).
